Recently I've noticed every once in a while my throttle will act up and either jump into high r's up and down or my car will die completely, it only happens when in gear... Also on the occasions it looks like its about to die, if I give it gas it will say it's at 2.5-3k rpm but the car is completely dead just coasting.. If I notice it happening then throw it in neutral wait a second and go back into gear it stops tweaking out for a little bit.. Motor is a b16a3 bottom end w/ a b16a2 head & p28 ecu.. I've been told it can be a tune problem, but wanted some second opinions before I go spend the $$

 

Anyone?

 

Might just get a retune and see if it helps.

 

this happened to me because of my icm in my dizzy once, then again when the screw holding the rotor in place came out. then again because if the icm.

 

Sounds like a fueling issue...how old is the fuel pump?

 

Not quite sure, I do know it was tuned kinda rich so it dumps a lot of fuel in general, especially when cold.

 

Any way to check a fuel pump?

 

turn the key to on and listen to it prime.

 

-.- I feel stupid, haha. It's not the fuel pump.

 

123

 

if fuel pump primes every time i would bet on the dizzy

 

Wouldn't a bad dizzy throw a CEL?

edit- does anyone agree that it could be caused by a poor tune?

 

not all the time actually it seems rare that it does indeed throw a cel. if it was in the tune it shuld be consistent not some random jump

 

Makes sense, I'll check out the dizzy in a bit.
